The present invention relates to a display stand, and more particularly, to a display stand with bending tubes having highly increased weight load capacity and enhanced overall structural strength.
Due to the progress in the display manufacturing techniques, many electronic products, such as video displays and interactive whiteboards, not only become bigger and bigger in size, but also becomes much heavier than before. Therefore, it is an important task for the display related manufacturers to develop a mounting device strong enough for mounting the big-size display.
Presently, the display mounting devices can be generally divided into two types, i.e. a wall-mount type and a mobile-stand type. The mounting devices of the wall-mount type are usually applied to general displays such as television display, which do not need to be moved and are frequently fixed on a wall, and this type of mounting devices has a simple structure.
On the other hand, the mounting devices of the mobile-stand type are designed to move freely to meet actual need in use and can provide high flexibility in use. However, the supporting strength of the mounting devices of the mobile-stand type display must pass the authentication tests certified by relevant organizations, such as Underwriters Laboratories Inc (UL), in order to ensure the safety of use.
Most of the currently available mobile-stand type display mounting devices are assembled from square tubes or round tubes which are connected to one another by welding. Such a manufacturing process is cumbersome and the manufacturing time is long. After the welding, the surface with weld seams must be polished, which inevitably reduces the overall structural strength of the supporting tubes.
In view of the above drawbacks, display related manufacturers are desired to develop a high structural strength display stand which is improved compared to the conventional display mounting devices and can be more simply manufactured with less process time.
To solve the problems of the conventional display mounting devices, a primary object of the present invention is to provide a high structural strength display stand with bending tubes which has high weight load capacity.
Another object of the present invention is to provide a display stand with bending tubes that has significantly enhanced overall structural strength.
A further object of the present invention is to provide a high structural strength display stand with bending tubes, which involves greatly simplified manufacturing processes and requires less manufacturing time.
To achieve the above and other objects, the high structural strength display stand with bending tubes according to a preferred embodiment of the present invention includes a lower supporting unit, an upper supporting unit and a foot rack. The lower supporting unit has a plurality of lower supports, each of which comprises a first and a second bending section spaced from each other. The upper supporting unit has a plurality of upper supports, each of which comprises a third and a fourth bending section spaced from each other. The foot rack is arranged adjacent to the lower supporting unit and assembled to the lower supports, such that the foot rack and the lower supports are juxtaposed.
With the first and second bending sections on the lower supporting unit, the third and the fourth bending sections on the upper supporting unit, and the fifth and sixth bending sections on the foot rack, the display stand of the present invention is capable to support a display unit up to 400 Kgs (follow UL1678 standard). The display stand with bending tubes not only has enhanced structural strength and highly increased weight load capacity, but also possesses the advantages of significantly simplified manufacturing processes and less processing time.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiment and the accompanying drawings, wherein:
The present invention will now be described with a preferred embodiment thereof and by referring to the accompanying drawings.

However, in practical implementation of the present invention, the number of the upper supports 210 is not necessarily limited to two. Each of the two upper supports 210 has a lower end correspondingly connected to an upper end of one of the lower supports 200; and each of the two upper supports 210 comprises a third bending section 2100 and a fourth bending section 2101. The upper support 210 upwardly extends from a vertical part to the third bending section 2100 and then extends in a substantially horizontal outward direction to the fourth bending section 2101, at where the upper support 210 extends upward, such that the fourth bending section 2101 is located away from the third bending section 2100 by a predetermined distance. Further, the two upper supports 210 are arranged in a way such that the two third bending sections 2100 are located side by side while the two fourth bending sections 2101 are located opposite to one another and directed towards two different directions.
It is noted the lower supporting unit 20 and the upper supporting unit 21 illustrated in the preferred embodiment of the present invention are not integrally formed. However, it is understood, in other operable embodiments, the lower and the upper supporting units 20, 21 can be otherwise integrally formed according to user's actual requirements.
According to the preferred embodiment, at least one connection unit 25 is internally provided at a joint of the lower supporting unit 20 and the upper supporting unit 21. The connection unit 25 has two ends that form an upper connection section 250 and a lower connection section 251. The upper connection section 250 is correspondingly connected to the upper supports 210 and fixed thereto by inserting a first fastening element 26 through the upper supports 210 and the upper connection section 250. The lower connection section 251 is correspondingly connected to the lower supports 200 and fixed thereto by inserting a second fastening element 27 through the lower supports 200 and the lower connection section 251.
